1. Every ebike has a way of measuring rear wheel rpm to obey the legal speed support. It is not hub or a mid drive specific thing. Hubs use motor position sensor for this one instead of an additional magnet type sensor that most of the mid drives use. So hubs measure motor rpm and this is also...

There are so many posts that answer your question. Instead of stating your uneducated opinion read them. Lag/feel has nothing to do with the motor position it is a matter of controller/sensor configuration.

You shouldn't change the number of links. Your previous chain is already working in the range of cogs in 11-42 cassette, since it is a subset of 11-50 so things should be fine.

Come on man, I live in a hilly part of Bay area, there are many %15+ grade hills in my neighborhood. In my new place I can literally open my door and begin climbing. Mountains/hills don't only exist in Europe. Besides aren't you living in an almost flat city? While I don't need any assistance...

With the speed limits in EU one can increase the reduction ratio and make a bike with a small hub motor which will climb well. This will limit the max speed but it is limited by law anyways. I guess that is what Van Moof did and people seem to be happy with its climbing ability.

Looks very good @Ravi Kempaiah . Some minor comments. -What is the handlebar sweep angle? Usually up to 15 it is good but afterwards it may be hard on the wrists. -Connecting the rack to the frame with 2 beams can be better. -Can front fork's travel be reduced? Braking at higher speeds may...

I really like the titanium frame. I think this frame is designed for belt/igh with a cutout. Probably with a derailleur one needs a spacer to prevent cross chaining. I wonder if the chain still skips when assist is off or low? On the bright side there should be an easy fix and if one day op...

I like 2 the best then 4. All the best.

I was about to ask you why don't you go for a front derailleur with that one. Even 2 chainrings on the front will greatly increase its range and you can still use a thick chain with it. Pinion's 9 speed offering beats the 14 speed rohloff in terms of range (~570 vs 550) or adding a front...

This. The funny thing is, if we had the distribution of time on each gear, I am certain that even for most of regular cyclists the distribution would be heavily falling on <8 gears let alone the ebike crowd here. The mathematics is also simple. The reason why you need an additional gear is, if...

Don't agree with what ? Assuming that what you mean by riding it like a regular bike means with little or no assist then that is pretty much a regular bike and rohloff is built for that. Also do you own a Rohloff? Didn't you have a 10 speed derailleur on your bike ?

14 is way too much. This is designed for a regular bike so that the rider stays with in the optimum power band at a given cadence as much as possible. With the addition of motor power that band significantly widens. 7-9 gears with a similar range would be much much better for ebikes.

:). To the best of my knowledge, 1. Any tdcm, dapu, gmac can take the cassettes you have mentioned. I think the misconception is a result of the entry level ebikes which use low level components. 2. Klever, Mtbcycletech and lately Stromer (new st3) has released ebikes with pinion/hub setup...

I like your bike setup a lot but here I have to disagree with most of these statements. 1. No, hubs can take those cassettes/derailleurs. 2. Pinion + hub setups are just as good if not better than rohloff etc since the igh does not have to be stressed with motor input. 3. There are through...

Most LBS' are not proficient at fixing electrical issues. For the mainstream mid drives they simply take out the motor and replace it which can be done by anyone. For the bicycle specific stuff I never had a problem taking and getting it fixed at a lbs. If they are refusing to work on...

What better options are there ?

Yeah, but you are the one who brought those subjects up first (mtb, gravel bike etc.).

@jodi2 We are on the same page for the most part. Mountain biking is a different animal. On technical terrain, off road you need to manipulate the whole body of the bike, hopping on it etc. and that is where they shine. I have a different opinion than yours on gravel bikes though. I have a...

Funny, I almost exclusively ride my Stromer at level 1, until last month I regularly climbed %20 grade sections for exercise at level 1(my consumption is around 11wh/mile depending on the speeds I keep). While it is not the true Stromer experience I still find it to be quite powerful at level 1...

Because there is a clutch at the rear wheel. For regen braking to work, when the wheel turns the motor always has to turn with it. However when you stop pedaling the wheel will keep on turning without turning the chain or the motor. There needs to be a significant design change to make regen...
